Thanks Kim.

That's very helpful.

One more question, to get teh RAM of the system,  is the way r190599
reliable? Could we trust env variable to get memory reading from bios?   

If I would like to calculate the RAM from 

totalmem = physmem << 12 + reserve_memory+ msgbuff_size

How can I get size of reserve_memory, i belive msgbuff_size is 65536?

THANKS
